Preboot Execution Environment

Preboot Execution Environment
In computing, the Preboot eXecution Environment (PXE) specification describes a standardized client-server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients. On the client side it requires only a PXE-capable network interface controller (NIC), and uses a small set of industry-standard network protocols such as DHCP and TFTP.

• In order to setup PXE server, you need to have a working DHCP and TFTP servers. DHCP server is used to distribute the IP addresses for the network systems, so that the client systems can communicate with PXE server. And, TFTP server is used to download the installation files from PXE server and send them to the PXE clients. We can deploy PXE, and DHCP servers on the same system or use different systems for each server. Due to lack of resources, I have tested this on a single system. You can either use a separate system or single machine for all servers.

The setup that requires here is basically one PXE server and one Host that will be the PXE client
The Services required on the PXE Server:
1. TFTP
2. DHCP
3. NFS

Power cycling

Power cycling is the act of turning a piece of equipment, usually a computer, off and then on again. Reasons for power cycling include having an electronic device reinitialize its set of configuration parameters or recover from an unresponsive state of its mission critical functionality, such as in a crash or hang situation. Power cycling can also be used to reset network activity inside a modem.
